to intimidate with harsh words or threats; bully
In the typical case, FBI agents do not initially take a man into custody for questioning, but interview him at his home or place of work. They ask him casually about the offense, not probing too deeply on the first try. The agents do not bully or browbeat the suspect into incriminating himself. They operate on precisely the opposite theory, that the suspect’s normal reaction will be to try to exculpate himself. Rarely will the suspect refuse to talk at all, for he fears that this will be taken by the agents as an admission of guilt.
